Revealing mistake: While Indy and Marion are in the Well of Souls, and they encounter the snakes, Indy falls to the ground only to be confronted by a hissing Cobra rearing its head. Look carefully and you'll see the snake's reflection on the safety glass between it and Indy. Briefly you can also see the torch's reflection while he's waving it around. You can also see Marion's reflection when she falls in later on and is face to face with the cobra. [This has been corrected in the new DVD set. You can only see it if you have the original VHS. I think it's visible in the "making of" on the DVD as well.]

Revealing mistake: In one scene just before the attack on a big Hunter the young captain (Jürgen Prochnow) is sitting with his charts. Beside him he has got a glass of beer standing. The sub lurches heavily right and left in the hard weather, but the surface of the liquid stays the same.

Revealing mistake: When Wally is firing the laser at random from the small spaceship, we see Fidget running down some stone stairs, and there are violent laser impacts directly behind him that could only have hit where they did if they had passed right though his body. (01:41:55)
Revealing mistake: 'Nightwind', the film at the centre of the drama, has finished shooting, and has been edited and postproduced, has premiered and bombed. All of this would take months - for a major production, up to a year. So why are the sets still standing on the studio sound stages?
Revealing mistake: When the father moves to close his dead daughter's eyes, the daughter's eyes close before the fathers fingers close them.
Revealing mistake: When Norman and Billy crash the boat, the side panel rips off of it before they hit the rock.
Revealing mistake: When Hauk finds the president's escape pod, there is a fire burning on the right of the screen. The camera was poorly placed in this part as the fire is horribly reflecting in the lenses, causing a bad distortion on screen that is highly distracting and covers the pod. (00:15:05)
Revealing mistake: When Joe has died of blood poisoning there is a close up of his head and neck, you can see him breathing and his eyes flicker.
